A new concept for resource oriented federal research within the competence of the German Ministry of Food, Agriculture and Consumer Protection was implemented in 2008. The Johann Heinrich von Thünen-Institute, Federal Research Institute for Rural Areas, Forestry and Fisheries is one of 4 newly established large scale federal research institutions. It comprises the former Federal Research Centre for Fisheries, the Federal Research Centre for Forestry and Forest Products and large parts of the Federal Agricultural Research Centre. The institute is named after Johann Heinrich von Thünen, a famous national economist and social reformer of the 19th century. He developed the first serious treatment of spatial economics (the so-called Thünen rings) and the basics of the theory of the natural pay.

Reports of cruises carried out off Mozambique between parallels 21 degree 00 and 26 degree 20'S and at depths of 400 and 800 meters including abundance indices, catch composition, geographic and bathymetric distributions of shrimp catches are presented. The main species found were Hymenopenaeus triarthrus and Aristeomorpha foliacea which represent 64 to 72% of total catches.

A survey of the Sofala Bank (Mozambique) was conducted to: estimate the abundance of shallow-water shrimp in the area between 16 degree 20'S and 20 degree 20'S, from 5 to 100 meters; estimate the shallow-water shrimp species composition and distribution pattern of main species. Collect biological data of the main species, Penaeus indicus and Metapenaeus monoceros; study the shrimp by-catch, species composition and biological data collection of the most abundant species of commercial value; and collect environmental data to clarify the shelf circulation on the Sofala Bank and the main oceanic features in the regions 15 degree S to 18 degree S and south of 22 degree S.
